Cloud Common Protos Laravel Package
google/cloud-common-protos
Generated PHP Protocol Buffer classes shared across Google Cloud APIs (part of google-cloud-php). Install via Composer as google/cloud-common-protos to use stable, Apache-2.0 licensed common proto message types in your apps.

Frequently asked questions about Cloud Common Protos
- Do I need to install `google/cloud-common-protos` directly in my Laravel app, or is it included via Google Cloud SDKs?
- You rarely need to install it directly—most Google Cloud PHP SDKs (e.g., `google/cloud-logging`) include it as a dependency. Only install it explicitly if you’re building custom protobuf-based services or need shared proto types without full SDKs.
- What Laravel versions support `google/cloud-common-protos`?
- The package itself has no Laravel-specific dependencies, but it requires PHP 8.1+ and the `google/protobuf` extension. Laravel 9+ is recommended for compatibility with modern PHP features used in Google Cloud SDKs.
- How do I handle protobuf immutability in Laravel’s Eloquent models?
- Protobuf objects are immutable, which conflicts with Eloquent’s mutable patterns. Use DTO mappers (e.g., `spatie/laravel-data`) to convert between protobuf objects and Eloquent models, or create adapters to bridge the two.
- Will this package work with Laravel’s service container?
- Yes, you can bind protobuf classes as Laravel service container singletons or resolve them dynamically. However, their immutability may require custom logic for dependency injection compared to traditional Laravel services.
- How do I serialize protobuf objects for JSON API responses in Laravel?
- Protobuf objects aren’t JSON-serializable by default. Use `$protobuf->serializeToJsonString()` or implement a custom serializer in your API responses. For requests, deserialize with `$protobuf->parseFromString($json).
- What are the deployment risks of the `google/protobuf` extension?
- The extension requires PHP compiled with protobuf support. Test your CI/CD (Docker/Kubernetes) or shared hosting environment early. If unavailable, consider pure-PHP alternatives like `prooph/pds`, though they lack Google Cloud compatibility.
- How do I handle deprecated protobuf fields (e.g., `ReservationResourceUsage`) in Laravel?
- Google’s protobuf schemas are backward-compatible, but deprecated fields may trigger warnings. Use feature flags or middleware to suppress warnings, or gradually phase out deprecated fields in your application logic.
- Can I use this package with Laravel’s API resources for structured responses?
- Yes, but you’ll need to customize API resources to serialize protobuf objects. Extend Laravel’s `JsonResource` or use a custom serializer to convert protobuf data into JSON-compatible arrays before rendering.
- What alternatives exist if I don’t want to use protobufs in Laravel?
- For Google Cloud APIs, alternatives include REST-based SDKs (e.g., `guzzlehttp/guzzle` for raw HTTP calls) or pure-PHP data structures. However, protobufs offer better performance and schema validation for gRPC or high-volume APIs.
- How do I test Laravel applications using `google/cloud-common-protos`?
- Mock protobuf objects in tests using PHPUnit’s mocking or create test doubles for dependencies. For integration tests, use in-memory protobuf serialization or mock the `google/protobuf` extension with libraries like `php-mock-extension`.
